Crop Factor
Crop factor is the ratio that compares a camera’s sensor size to a standard full-frame sensor and affects perceived focal length.

Crop factor indicates how much a smaller sensor crops the image relative to full frame. For example, a camera with a 1.5× crop factor makes a 50mm lens appear equivalent to a 75mm field of view. Crop factor does not change the lens itself, but it changes how much of the image is captured. This impacts composition, lens choice, and depth of field. Filmmakers must account for crop factor when switching between camera systems to maintain consistent framing. Crop factor can be advantageous for telephoto shooting but limiting for wide-angle compositions.

Crop factor changes framing perception — it determines how lenses behave on different cameras.
